Wash. Rev. Code § 48.21.370
The commissioner shall adopt rules setting forth the content of a standard disclosure form to be delivered to all applicants for group illness-triggered fixed payment insurance, hospital confinement fixed payment insurance, or other fixed payment insurance. The standard disclosure shall provide information regarding the level, type, and amount of benefits provided and the limitations, exclusions, and exceptions under the policy, as well as additional information to enhance consumer understanding. The disclosure shall specifically disclose that the coverage is not comprehensive in nature and will not cover the cost of most hospital and other medical services. Such disclosure form must be filed for approval with the commissioner prior to use. The standard disclosure form must be provided to the master policyholders at the time of solicitation and completion of the application and to all enrollees at the time of enrollment. All advertising and marketing materials other than the standard disclosure form must be filed with the commissioner at least thirty days prior to use.
